- Hadean (Wikipedia)
The Hadean (IPA: /heɪˈdiːən, ˈheɪdiən/ hay-DEE-ən, HAY-dee-ən) is the first and oldest of the four known geologic eons of Earth’s history. The Hadean eon started with the planet’s formation about 4.54 Bya, now defined as (4567.30 ± 0.16) Mya set by the age of the oldest solid material in the Solar System found in some meteorites about 4.567 billion years old. The proposed interplanetary collision that created the Moon occurred early in this eon, and the Late Heavy Bombardment is hypothesized to have occurred at the end of the eon. The Hadean ended 4.031 billion years ago, and was succeeded by the Archean eon.
- Cyberpunk (Wikipedia)
Cyberpunk is a subgenre of science fiction in a dystopian futuristic setting said to focus on a combination of “low-life and high tech”. It features futuristic technological and scientific achievements, such as artificial intelligence and cyberware, juxtaposed with societal collapse, dystopia or decay. Much of cyberpunk is rooted in the New Wave science fiction movement of the 1960s and 1970s, when writers like Philip K. Dick, Michael Moorcock, Roger Zelazny, John Brunner, J. G. Ballard, Philip José Farmer and Harlan Ellison examined the impact of drug culture, technology, and the sexual revolution while avoiding the utopian tendencies of earlier science fiction.
